    Righto chaps and chappettes..

     

    Last week I bought some non-descript Rhinogobius which I think are R.duospilus. not all are the same, although I think that could just be down to stress colouring and dominance/territory issues.

     

    I’ve currently got them in a quarantine tank but wondered if anyone with more knowledge of the Family etc could help pin it down with more accuracy. r1.jpgr2.jpgr3.jpgr4.jpgr5.jpgr6.jpgr7.jpgr8.jpg

    Hi Chris,

    there are different species. The female could not be identified and I hope, you have one for any male.

     

    The first pic is too dark to be sure. But I suspect, it is a R. cf. nandujiangensis.

    The second and third pic is a female with nematodes. She needs to be dewormed.

    The fourth pic shows a young male, not well developed. I can’t say anything about him.

    The fifth and sixth pic seems to be a pair of R. ponkouensis, but not sure.

    About the last pics I can’t say anything.

    Thanks for responding so quickly Jutta. Much appreciated.

     

    I bought the fish last week from a small chain petshop in England for £2.40. Just labelled as Gobies and no other info. They were dotted around the tanks rather than being in one specific one. They are in quarantine at the moment to feed them up as some really are thin. There are 8 in total however 3 or 4 are rarely seen. I will persevere and try to get better pics of them, especially individually for further reference.

    I wonder if this fish is related to the import in the US I asked you about a couple of weeks ago…. looks equally malnutritioned and makes one think of worms …. I’m still tempted to get them a bit :(

    Chris, definitely de-worm them asap.

    I know that these fish have been in the shop a while now. I don’t think they have been fed a proper diet at all. The tank they were meant to be in had the best specimens that you see in my pics. The others came from the tanks surrounding that one and are all the thinner ones. The lass who served me didn’t know anything about them at all. I got them not just because they’ve been an always want fish but earlier in the year I left them in the shop and regretted it ever since, when I called in and saw they were still there I decided to take as many as I could.

    There are more back in the shop that I hope to pick up on Friday. I’ll dose the wormer asap.

    The most duospilus-similar from China are infected with nematodes. In principle it is always the first requirement if you buy them to deworm them. Only then can you really say something about them, because then they only develop properly.
